I have to say that these are the best water pills you can get. Diurex Water pills are very effective when it comes to relieving bloat and excess water weight. It’s good for bloating, swelling, fulfilling fatigue associated with pre-menstrual and menstrual periods as well the side effects it may cause nervousness, irritability, sleeplessness, occasional rapid heartbeat, but that’s because they contain about as much caffeine as one to 2 cups of coffee. The active ingredient and these pills are mainly caffeine and this diuretic uses for the relief of temporary water retention, bloating and swelling. For the dosage, they say to take one or two pills every 3 to 4 hours, but do not exceed eight pills in a 24 hour period. Make sure you read the label on your packaging. It’s usually has it all in the back so make sure you follow what it says on your label and not just go by what someone else says or refers you to do reading the label is very important to your health. But these water pills are very effective and I use them when I feel really bloated or at times like right now when I am on my period or on my cycle and have some bloating or excess water weight, this will get rid of it but the only thing is you must drink a lot of water Because you’ll start to urinate a lot and you can possibly become dehydrated if you don’t drink enough water while taking these pills. Also don’t be alarmed but you might turn green because of the blue dye in the pills but you will definitely have to go to the bathroom very often so if you’re going to take these pills, just make sure you’re going to be able to access the bathroom because you’ll be peeing a lot lol but it will help you feel a lot less bloated and you will feel lighter afterwards so that’s why I really love these pills. These are my go to water pills to get rid of excess water weight and bloating and I’ve never experienced any really bad side effects from taking these other than being a little too wide awake because of the caffeine in it or just having to pee a lot Getting dehydrated when I don’t drink enough water behind it so again, make sure you drink a lot of water when you take these pills at least eight ounces of water behind it. But I highly recommend and ladies if you’re on your period, these will make you feel really good and a lot less bloated and get rid of that excess water, weight and bloating
